Muscle length for the triceps is done by flexing the elbow and shoulder
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because flexing both the elbow and shoulder joints is required to fully lengthen the triceps muscle. When the elbow is flexed, the triceps muscle is shortened, and when the shoulder is flexed, it further stretches the triceps muscle. Therefore, both movements are necessary to achieve the maximum length for the triceps muscle.Rate this question:
